Dianella revoluta 'Little Rev'

The Story

Plant Bio

Dianella revoluta, commonly known as the blueberry lily or blue flax-lily, is a tufted evergreen perennial native to dry forests and open woodlands across mainland Australia and Tasmania. The species spreads via short underground rhizomes to form dense clumps of narrow, leathery leaves with distinctly rolled margins.

'Little Rev' is a compact horticultural selection distinguished by its strictly upright, architectural, fan-like growth habit that reaches only 30 to 40 centimetres in height. The foliage exhibits a pronounced blue-grey to blue-green coloration, which remains vibrant throughout the year under proper drainage conditions.

Uses & Benefits:

Provides a highly structured, blue-grey architectural accent with upright, fan-like foliage and delicate purple-blue flowers.

Highly drought-tolerant once established, making it suitable for low-water landscapes, coastal zones, and erosion control on slopes.

Supports native bees and beneficial insects, while the dense foliage provides cover for small insectivorous or seed-eating birds.

How to Grow

Select a planting site in full sun to moderate shade with free-draining soil.
Dig a hole twice the width of the root ball but of equal depth, ensuring the plant sits slightly elevated.
Backfill with native soil, firming gently around the root ball without burying the crown.
Water thoroughly to settle the soil, then apply a thin layer of coarse mulch, keeping it clear of the foliage base.

Pro Tip

Avoid planting this cultivar in low-lying garden depressions or burying the crown beneath soil or mulch, as trapped moisture at the base rapidly triggers fatal root rot.

Keep It Thriving

Care Guide

Do

Plant in raised beds or sloped landscapes to guarantee excellent drainage.
Prune the foliage back hard to one-third of its height every three to five years to rejuvenate growth.
Use standard native-plant low-phosphorus or balanced slow-release fertilisers if feeding is required.

Don't

Do not plant the crown below the soil or mulch line.
Do not overwater or allow the plant to sit in waterlogged depressions.
Do not prune heavily on an annual basis, as this stresses the plant.
